Hey, thanks for trying the demo.
Good to know that it works there as well.
As mentioned in the readme file, I don't know much about Linux so I'm assuming an "aur" script basically installs the game and probably dependencies as well?
I might install Manjaro in a VM and try it out there myself so I have more of an understanding about how it works.
If it's not too time consuming I could possibly start to at least semi-support that as well (and possibly include that script link in the install instructions), but we'll see.
Anyway, thanks for the feedback. :)
